Transport, installation and assembly

3.2 Protection of the cooling water ducts for the water-cooled version

Storing indoors
Store the motors in storage rooms that
● Are dry, dust-free, frost-free and vibration-free
● Are well ventilated
● Offer protection from extreme weather conditions
Protect the motors from shocks and humidity.
Preservation (mothballing)
If the motors are going to be stored for a period longer than six months, you must check their
condition every six months. Check:
● The bearing grease
● The motor for damage
Carry out the necessary servicing and preservation work. Document all preservation
measures taken so that they can be reversed before the motors are put back into service.
Always slightly heat the motor windings. Ensure forced air ventilation.
CAUTION
Condensation water
The motor is equipped with condensation water drain holes. Regularly remove the screw
plugs. Allow the condensation water to drain and then replace the screw plugs. [ID 812.01]

3.2 Protection of the cooling water ducts for the water-cooled version
Protection of cooling-water ducts during storage
The cooling-water ducts are protected by an anti-corrosion agent when the motors are
delivered from the factory. The ducts on delivered units are empty to protect against frost
damage.
NOTICE
Corrosion protection
If the cooling water has been removed, you must flush the cooling circuit with an anti-
corrosive agent if the motor is going to sit idle for a long period of time.
